Yes - totally agree. Looking to break out of the ISO performance of my T1i, but it's less about crop vs. FF, and more about what leaps in ISO improvement mean - regardless of format.

But you involved the format, like it or not, in your question. The "ISO performance" is better on FF because of the format, not because of better sensors. And then there are so many other variables. You cannot ignore the format.

And by "only" 1 1/3 stops - about the same as f/2.8 versus f/4!
